Creamy Soup Lovers
If you love creamy soups, this recipe is made for you. It’s easy to prepare, uses straightforward ingredients, and delivers a rich, velvety texture without heavy cream. Roasting the vegetables first intensifies their flavor, and then blending them with broth creates a smooth, comforting soup. Finish with classic loaded-baked-potato toppings—bacon, green onions, roasted red peppers, and shredded cheddar—to make it irresistible.
How to Make Potato Soup
This cauliflower potato soup comes together in a few simple stages: roast, reserve, blend, simmer, and serve. The technique is forgiving and easy to adapt based on how thick or chunky you like your soup.
Step 1: Prep and Roast
Preheat the oven to 450ºF. Toss quartered potatoes, chopped cauliflower, chopped onion, whole smashed garlic cloves, olive oil, minced fresh rosemary, salt, and pepper together on an oiled baking sheet. Roast until the vegetables are tender and lightly browned, about 30–40 minutes, stirring once halfway through to ensure even browning.
Step 2: Reserve a Cup
After roasting, scoop out about 1 cup of the mixed vegetables and set them aside. These reserved pieces are added back later to create a bit of chunk and texture in the finished soup.
Step 3: Blend the Base
Place the remaining roasted vegetables in a blender, add 3 to 4 cups of chicken broth (or vegetable broth to keep the soup vegetarian), and blend until smooth. For a thicker soup use less broth; for a thinner, more pourable soup, add more broth.
Step 4: Simmer
Pour the blended soup into a large stockpot, add the reserved cup of roasted vegetables if you’d like some chunks, and bring to a gentle boil. Reduce heat and simmer for 10–15 minutes to allow flavors to marry and the soup to thicken slightly.
Step 5: Serve and Enjoy
Ladle the soup into bowls and top with diced bacon (or bacon bits), chopped green onions, roasted red peppers, and shredded cheddar cheese. These toppings echo the flavors of a loaded baked potato and add color and texture.
Storing Loaded Potato Soup
Store the cooled soup in an airtight container in the refrigerator or freezer. In the fridge it will keep for 5–7 days. For longer storage, freeze portions for up to 3 months. If you plan to freeze, avoid adding cheese or delicate toppings until you reheat and serve.
Freezing and Thawing Tips
This soup freezes well. If frozen after adding dairy toppings, the texture of cheese can change when thawed—so it’s best to freeze before adding cheese. Thaw overnight in the refrigerator before reheating on the stovetop over low heat. Thawed soup can thicken; add additional broth or water to reach your desired consistency.

More Ways to Use Cauliflower
Cauliflower works wonderfully beyond soup: try roasted cauliflower salads, cauliflower wings with Asian or buffalo sauces, cauliflower casseroles, or cauliflower mixed with grains for hearty bowls. Its mild flavor and meaty texture make it a great ingredient to experiment with.
